- 摘要:
- 分析了海南前兆台网水位仪对苏门答腊MS 8.7地震和我国四川汶川MS 8.0地震的高采样率水震波记录情况，从中可较明显地看到地震波引起的井水位详细变化，但也存在水震波的丢头、仪器时间存在误差，第一代仪器水震波相互覆盖等现象，提出了在水位仪中增加在线缓存记录、自动定时校时功能等改进建议。
The high sampling rate waterseismic waves about SumatraAndeman strong earthquakes and Wenchuan earthquake recorded by waterlevel meter of Hainan digital seismic precursor network were analyzed. The detailed variations of well waterlevel caused by seismic waves can be distinguished from the waterseismic waves. But there were some problems, such as the heads of waterseismic waves were missed recording, time errors of waterlevel meter relatively great and waterseismic waves recorded by the first generation waterlevel meter sometimes were covered each other. The some improvements: such as adding function of data online cache and automatic correcting time in waterlevel meter were put forward.
